Cygnus, the Orbital Science spacecraft headed for the International Space Station, is in orbital limbo. A week ago today, the company's Antares rocket blasted the capsule into space toward an expected rendezvous with the ISS. When the Cygnus reaches the station, Orbital will join SpaceX as the only companies to reach ISS with their own privately built spacecraft.

Orbital had planned to reach the station this past Sunday, then delayed the ETA to today, Wednesday, because of a software glitch. Now, Cygnus will have to wait a little longer to make the connection. Space.com reports that the station's newest crew is headed there today aboard a Russian Soyuz spacecraft, and NASA says it wants them to have a few days to get settled before they have to deal with bringing a brand new ship to the ISS.

It's no problem for Cygnus. Orbital says the craft can stay in its orbit around Earth for an "extended period of time" until the space station is ready for its arrival, at which point it will adjust course to catch up to the ISS and deliver its cargo load. The meet-up is now set for Saturday.
